Spud Core…

When Mr. Murphy left this existence, he passed the course to his daughter, Lilith. Lilith founded “Spud Core” as a group to protect and preserve the integrity and benefits of this amazing course by keeping its core values. Spud Core is comprised of EIS® graduates with experience in various areas of music business. Together they run the activities of the Equal Interval System® course and business. The success of our students is our primary goal.
